First of all, GitOps requires that your deployment artifacts are already there. This means that tasks such as… ● Compiling code ● Running unit/integration tests ● Security scanning ● Static deployment part of an application artifact. The full software life cycle includes several other tasks until that point that deals with the packaging of the artifact, the unit tests, security scanning GitOps tools focus only on the deployment part of the release cycle and ignore all other associated tasks. You could argue that this is their primary focus and they don’t have to provide anything else regarding

They can work in a world they know, using pull requests to accelerate deployment and operations tasks. The benefits for development teams include increased velocity and improved system reliability. your organization. Not only will all your CI/CD pipelines be driven by pull request, but operations tasks will also be fully reproducible through Git. 6. Stronger security guarantees With strong cryptography

continuous integration and continuous deployment pipelines all driven by pull request, but your operations tasks are also fully reproducible through Git. 6. Stronger Security Guarantees Git’s strong correctness This is significant on two levels: 1. It is more secure. 2. It automates complex error prone tasks like having to manually update YAML manifests. With the operator pattern, an agent acts on behalf

Repository and Directory Structures When adopting GitOps, organizations must plan carefully to divide tasks and config- uration files appropriately between repositories and directories in each repository. the deployment, a postsync hook can trigger additional pipelines to perform any post-deployment tasks. The model is illustrated in Figure 6-3. Figure 6-3: The CI-triggered and GitOps-owned method.

Streamlined, automated pipelines GitOps translates all the manual, complicated infrastructure management tasks to a streamlined, automated pipeline. This declarative version-controlled approach makes the time-

Code Transitioning to a cloud-native architecture also brings about an increase in maintenance tasks. The dynamic and distributed nature of cloud-native applications requires continuous monitoring
